SAND-DRIER.

SPECIFICATION forming part of Letters Patent No. 267,838, dated November 21, 1882.

' Application filed September 28, 1882. (No model.)

To all whom it may concern Beit known that 1, WILLIAM W. CLARK, a citizen of the United States, residing at Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Sand-Driers, of which the following is declared to be a full, clear, and exact description, reference being had to the accompanying drawings, wherein- [0 Figure 1 shows the drier in longitudinal central section. Fig. 2 showsa portion of the drier in side elevation; and Fig. 3 is a detail view, in longitudinal section, of a portion of the guide-ring and hopper.

Sand that is ordinarily carried in suitable receptacles upon a locomotive-engine to be sprinkled at times upon the rails immediately in front of the drivers, so as to promote traction, should be well dried to prevent clogging in the delivery-pipe, and to'secure a thin and even distribution of the same upon the rails. My invention relates to apparatus designed to expel moisture from sand and analogous material; .and it consists of certain improve- 2 ments in the construction of driers, allashereinafter described and claimed, whereby sand or the like may be quickly, cheaply, and thoroughly dried.

Referring to the drawings, A represents the 0 casing of a stove or furnace, conveniently madein several sections, fitted to each other, as shown, for ease in removal and replacement, said casing A resting upon an annular ring or flange, B, that is sustained upon the walls of the ash-pit C and external thereto, so

as to be free from contact with the furnacetire. The upper part or face of the stovecasing A is preferably made rounding or inclined, as at a, so that the sand may not lodge 4o thereon to cut or corrode the metal, and at the same time that the furnace -flame may have something of a reverberatory action on the damp materials. A grate, D, separates the ash-pit from the fire-pot, which latter is 5 charged with fuel through a fire-box, E, that is fastened to the casin g A and projects therefrom, being closed at its front end by the door F. A hopper, G, of sheet metal or the like, shaped somewhat as an inverted conefrustum, surrounds the furnace A, and rests at its lower end in a flaring seat formed in an annular rim or ring, 9, having a series of perforations, g,in its face, and supported upon a ledge of the flange B. The rim 9 may be riveted or otherwise securely fastened to the hopper G, if desired, or may be dispensed with entirely. In either event the perforations g will be located with reference to the sloping face 11 of the flange B in such manner as will permit the dried sand to be freely and rapidly '60,

discharged when it arrives at said perforations without chance-to stick upon or to corrode the flange B. It will be noted, moreover, that the upper wall or face of the feed-box E,where the same crosses the space occupied by the 6 sand between the furnace A and the hopper G, is made transversely inclined or sloping,

as at 0, instead of being flat, so that the sand may not be retarded in its descent, nor the box be subjected to the destructive cutting action which results when the sand is lodged thereon. Byhaving the perforations g in position shown, convenient access is afforded to any one of them which may become clogged by gravel or the like. At the same time the sand is projected by the sloping face b, and falls freely away from the base of the stove for collection. If a fire be burning in the stove the damp sand fed into the mouth of hopper G will descend gradually therein down and around the casing A and feed-box E, becoming thoroughly dried in its passage, and be discharged through the perforations g. The slope given to the several parts, as hereinhefore described, effectually prevents the 8 5 sand from sticking at any point, so that there is no destructive cutting of the metal.

Having thus described the invention,,what

I claim as new and desire to secure by Letters Patent, iso 1. In a sand-drier, the combination, with the stove or furnace casing and with the hopper, of a feed-box having its upper face trans versely inclined, substantially as set forth.
